Excitation of multiple surface plasmon-polaritons(SPPs) by an equichiral sculptured thin film with a metal layer defect was studied theoretically in the Sarid configuration, using the transfer matrix method. Multiple SPP modes were distinguished from waveguide modes in optical absorption for p- polarized plane wave. The degree of localization of multiple SPP waves was investigated by calculation of the time averaged Poynting vector. *The resultsshowed that the long-range and short-range SPP waves can simultaneously be excited at both interfaces of metal core in this proposed structure which may be used in a broad range of sensing applications.* When multiple dissimilar metal layers are uses to form Surface Plasmon Polaritons(SPP), each separate layer generates it own unique polariton SPP waveform. This could possibly means that the number of polaritons is multiplied by the number of metal layers used. I wonder is a mush using multiple micro layers of nickel, palladium, and titanium would produce three times the polariton population.
